Another thing that made life so rich in the RN was the rich diversity of nicknames, usually 'allocated' during the first draft after basic training, they stuck with the owner until the day they left the Andrew. Woe be tide anyone with a physical 'defect' as this would be picked up in seconds by your oppo's and as they say - "A nickname's for life, not just for Christmas!"
This list is by no means exhaustive, and obviously a 'deformity' or 'memorable act' nickname would 'trump' a 'place of origin' nickname! Therefor A Jones or Davies from Wales would for example forgo 'Taff' for a more fitting nickname! In my time in the RN I can still remember 'One Bollock' B*****n, A Gunnery Officer called 'No legs', a 'Two bits' L*******t, and a black Cook who insisted his name was 'Chip' but was instantly christened 'Kissy!" There are literally thousands more!
Below are some of the more common and printable nicknames used.
